Even with modern prevention and treatment advances, losing teeth in later life is still a sad but common part of human experience. Just as generations have before, many today rely on dentures to regain their lost dental function and smile.
But although effective, dentures have their weaknesses. The most serious: they can't prevent jawbone deterioration, a common problem associated with tooth loss.
Bone health depends on chewing forces applied to the teeth to stimulate replacement growth for older bone cells. When teeth are gone, so is this stimulation. Dentures can't replicate the stimulus and may even accelerate bone loss because they can irritate the bone under the gums as they rest upon them for support.
But there's a recent advance in denture technology that may help slow or even stop potential bone loss. The advance incorporates implants with dentures to create two hybrid alternatives that may be more secure and healthier for the supporting bone.
The first is known as an overdenture, a removable appliance similar to a traditional denture. But instead of deriving its support from the gums alone, the overdenture attaches to three to four implants (or only two, if on the lower jaw) that have been permanently set into the jawbone. This not only increases stability, but the implants made of bone-friendly titanium attract and foster increased bone growth around them. This can help slow or even stop the cycle of bone loss with missing teeth.
The second type is a fixed denture. In this version, four to six implants are implanted around the jaw arch. The denture is then secured in place to these implants with screws. It's a little more secure than the overdenture, but it's also more expensive and requires good quality bone at the implant sites.
If you've already experienced significant bone loss you may first need bone grafting to build up the implant sites for these options, or choose traditional dentures instead. But if you're a good candidate for an implant-supported denture, you may find it provides better support and less risk of continuing bone loss than traditional dentures.

One of the best and most successful tooth replacement choices available is the dental implant. No other restorative method is as similar in both form and function to a real tooth as an implant; and with a success rate of 95-plus percent after ten years, it’s one of the most durable.
But there can be extenuating circumstances that make obtaining an implant difficult or sometimes impossible. One possible problematic situation is the systemic disease diabetes.
Diabetes is a hormonal condition in which the body is unable to sufficiently regulate the amount of glucose (a basic sugar that provides energy to the body’s cells) within the blood stream. Normally, the pancreas produces the hormone insulin to reduce excess glucose. But diabetes interferes with this insulin production: if you have Type 1 diabetes, the pancreas has stopped producing insulin altogether; if you have the more common Type 2, the body doesn’t produce adequate insulin or it doesn’t respond sufficiently to the insulin produced.
Over time diabetes can affect other areas of health, especially wound healing. Because the condition gradually causes blood vessels to narrow and stiffen, the normal inflammatory response to disease or trauma can become prolonged. This in turn slows the rate of wound healing.
Slow wound healing can have a bearing on the recovery period just after implant surgery, especially the necessary integration process that takes place between the bone and the titanium metal implant that provides its signature strength. If that process is impeded by slow wound healing caused by diabetes, the risk increases dramatically for implant failure.
That’s the worst case scenario if you have diabetes, but only if your condition is out of control. If, however, you have your blood sugar levels well regulated through medication, diet and exercise, then your chances for implant success could easily be on par with someone without diabetes.
So if you’re diabetic and are considering dental implants for missing teeth, it’s important to discuss the possibility of obtaining them with both your dentist and the physician caring for your diabetes. With your overall healthcare team working together, there’s no reason why diabetes should stop you from enjoying this premiere restoration for missing teeth.

If you’ve just received a dental implant restoration, congratulations! This proven smile-changer is not only life-like, it’s also durable: more than 95% of implants survive at least 10 years. But beware: periodontal (gum) disease could derail that longevity.
Gum disease is triggered by dental plaque, a thin film of bacteria and food particles that builds up on teeth. Left untreated the infection weakens gum attachment to teeth and causes supporting bone loss, eventually leading to possible tooth loss. Something similar holds true for an implant: although the implant itself can’t be affected by disease, the gums and bone that support it can. And just as a tooth can be lost, so can an implant.
Gum disease affecting an implant is called peri-implantitis (“peri”–around; implant “itis”–inflammation). Usually beginning with the surface tissues, the infection can advance (quite rapidly) below the gum line to eventually weaken the bone in which the implant has become integrated (a process known as osseointegration). As the bone deteriorates, the implant loses the secure hold created through osseointegration and may eventually give way.
As in other cases of gum disease, the sooner we detect peri-implantitis the better our chances of preserving the implant. That’s why at the first signs of a gum infection—swollen, reddened or bleeding gums—you should contact us at once for an appointment.
If you indeed have peri-implantitis, we’ll manually identify and remove all plaque and calculus (tartar) fueling the infection, which might also require surgical access to deeper plaque deposits. We may also need to decontaminate microscopic ridges found on the implant surface. These are typically added by the implant manufacturer to boost osseointegration, but in the face of a gum infection they can become havens for disease-causing bacteria to grow and hide.
Of course, the best way to treat peri-implantitis is to attempt to prevent it through daily brushing and flossing, and at least twice a year (or more, if we recommend it) dental visits for thorough cleanings and checkups. Keeping its supporting tissues disease-free will boost your implant’s chances for a long and useful life.

Due to financial circumstances, people often have a lost tooth restored with a removable partial denture, an effective appliance that restores function and a degree of aesthetic appearance. Later, though, they may want to improve both function and appearance with a dental implant.
If this describes you, you’re making a great choice. Dental implants are the closest technology we have to a natural tooth. But there may be a roadblock to your implant, especially if a long time has passed since your tooth loss—there may not be enough bone at the site to place an implant.
The heart of an implant is a titanium metal post surgically imbedded in the jawbone. The titanium naturally attracts bone cells, which grow and adhere to it to form a solid hold that can support a porcelain crown or other restorations like bridges or dentures. But to achieve a natural appearance it’s important that the implant is placed in the right location. To achieve that requires adequate bone.
But there may not be adequate bone if the tooth has been missing for a while. The forces generated when we chew travel through the teeth to the jawbone, which stimulates bone growth. If that stimulus is absent because of a missing tooth, new bone cells may not replace older ones at a healthy rate and the total bone volume begins to diminish. A denture can’t compensate and, in fact, accelerates bone loss.
But there may be a solution: bone grafting. With this procedure we place a donor bone graft into the area of bone deficiency some time before implant surgery. The graft serves as a scaffold for new bone cells to grow upon. Hopefully, this will produce enough healthy bone to support an implant. If the bone deficiency is minor, we may place the implant and the bone graft at the same time.
If you have experienced bone loss, we must first determine the amount of bone at the missing tooth site and whether grafting is a viable option. Bone grafting postpones your implant, but the delay will be worth the wait if we’re successful. With increased bone volume you’ll be able to obtain a new tooth that’s superior to your current restoration.
If you smoke, you know better than anyone how a hard a habit it is to kick. If you want to quit, it helps to have a motivating reason—like lowering your risk for cancer, cardiovascular disease or similar conditions.
Here’s another reason for quitting tobacco: it could be making your teeth and gums less healthy. And, if you’re facing a restoration like dental implants, smoking can make that process harder or even increase the risk of failure.
So, to give your willpower some needed pep talk material, here are 3 reasons why smoking doesn’t mix with dental implants.
Inhaled smoke damages mouth tissues. Though you may not realize it, the smoke from your cigarette or cigar is hot enough to burn the top layer of skin cells in your mouth, which then thickens them. This could affect your salivary glands causing them to produce less saliva, which in turn could set off a chain of events that increases your risk of tooth decay or periodontal (gum) disease. The end result might be bone loss, which could make installing dental implants difficult if not impossible.
Nicotine restricts healthy blood flow. Nicotine, the chemical tobacco users crave, can restrict blood flow in the tiny vessels that course through the mouth membranes and gums. With less blood flow, these tissues may not receive enough antibodies to fight infection and fully facilitate healing, which could interfere with the integration of bone and implants that create their durable hold. Slower healing, as well as the increased chances of infection, could interrupt this integration process.
Smoking contributes to other diseases that impact oral health. Smoking’s direct effect on the mouth isn’t the only impact it could have on your oral health. As is well known, tobacco use can increase the risk of systemic conditions like cardiovascular and lung disease, and cancer. These conditions may also trigger inflammation—and a number of studies are showing this triggered inflammatory response could also affect your body’s ability to fight bacterial infections in the mouth. Less healthy teeth, gums and underlying bone work against your chances of long-term success with implants.
